Abstract (en)
Disclosed herein is a method of receiving a spread-spectrum signal in a radio communication terminal device having a plurality of demodulators for demodulating a received spread-spectrum signal, comprising the steps of detecting when at least one of a plurality of demodulators is incapable of properly demodulating the received spread-spectrum signal, determining whether or not there is a demodulator which is not being used other than the at least one of the demodulators, and continuing a demodulating process of the at least one of the demodulators, if there is a demodulator which is not being used. Thus, according to the present invention, the time in which the demodulator is unlocked is minimized, and a stable, high-quality signal can be received. <IMAGE>
